# Selling Base Cards

In Mission Control, you have the option to sell your Base Cards back to the game for store credit. Here’s a step-by-step guide to help you navigate this process:

**1. Access the Collection Page**

To begin, navigate to your **Collection Page**. This is where you can view all your owned Base Cards, along with their details and current status.

**2. Locate the Base Card You Want to Sell**

Browse through your collection to find the Base Card you wish to sell. Each card will have an option to manage or sell it.

**3. Initiate the Selling Process**

Click on the **Base Card** you want to sell. This will open a detailed view of the card, where you’ll find options for managing or selling it.

**4. Select “Sell” Option**

Look for the **“Sell”** button or link in the card details. Clicking this will initiate the selling process.

**5. Confirm the Sale**

You will be prompted to confirm your decision to sell the card. Review the details carefully, including the amount of store credit you’ll receive for the card.

**6. Complete the Transaction**

Once confirmed, the card will be sold, and you will receive store credit in your account. This credit can be used for future purchases in the in-game store.

**7. Check Your Store Credit Balance**

Return to the **in-game store** to view your updated store credit balance. You can now use this credit to buy new Base Cards or other items.

By selling Base Cards back to the game, you can manage your collection more efficiently and fund your future purchases, enhancing your gameplay experience.
